Topic: Add card to ati.c (Read 2765 times)

Hey guys. I'm kind of a newbie, so please bear with me here. I have the ATi Radeon HD 4550 Graphics Card, and have basically gotten it to work in Lion, but no Steam/Source games, like Portal 2, will launch. I read on the InsanelyMac forum, that it had to do with GraphicsEnabler. So I download the latest trunk, and looked at the ATI.c. There are 3 traces of my card. First, there are two under the first "list":

{ 0x954F,0x29201682, CHIP_FAMILY_RV710,"ATI Radeon HD 4550",kNull},{ 0x954F,0x29211682, CHIP_FAMILY_RV710,"ATI Radeon HD 4550",kNull},But these do not have my Device ID, 9540. The third occurrence is under the default model list:

{ 0x9540,0x00000000, CHIP_FAMILY_RV710,"ATI Radeon HD 4550",kNull},This has my Device ID, but does not have the subsys_id. How do I find my correct Device ID and subsys_id, so I can put in in the "non general" cards list? Do I use lspci? Thanks!
